I finally got the car up on stands and removed both calipers and treated the rotors, pistons, etc., and the brake pads I got from .net don't fit!!!! The protruding tabs at either end are two wide to slip into the channel of the outer caliper assembly.

Did I get the wrong pads for the SLK or am I missing something?

The box says AP 740 R4S. There are no other identifying signs. Any one have this box still with them to check?

The e-mail confirmation for the order says:

Description : Porterfield R4S Front brake pads for SLK230 $99

The big problem is I have the car up on jacks in the driveway and the pistons retracted fully. I cannot see putting back the almost worn brake pads and using it until I get the right brake pads.

If they are indeed wrong pads, then this is really irresponsible of Jerry.

I have no other transport to get to the dealer tomorrow and get the OEM pads. So I am stuck. Sigh!!!

As I suspected, it is the wrong pads. I found an application catalogue online. For any one who may stumble on this thread in the future while ordering these parts, do verify the part number if you order from Jerry BEFORE you dismantle your car!

The AP 740 is for the CLK not the SLK. I should have received the AP 710.

SLK pads numbers:

The first AP number is for front and the second for back along with list prices in US dollars.

SLK 230 4/97-01 AP 710 99.00 AP 779 89.00
SLK 32 2002 AP 682 169.00 AP 603 119.00
SLK 320 00-01 AP 740 99.00 AP 779 89.00

Not sure what happens to car years not listed above.

man that stinks. have you talked w/Jerry? I had a pretty good experience with him. Hope everything works out well.
Left voice mail and sent e-mail. I assume he is not working Sundays.

Unfortunately, any vendor can screw up (although my luck or lack of it has something to do with it as well, the last time I ordered winter tires with wheels from Tire Track, they sent three of the 4 directional tires mounted to be on the driver side).

What distinguishes good vendors from bad ones is how they handle the screwups. I will post how Jerry handles this after it is resolved.

I'm glad to see this post. I ordered a set of pads from him a few days ago. You can bet that I'll check the part number before I do anything else. Thanks.

Received e-mail reply from Jerry. He doesn't ship these orders. Porterfield in CA does. He says he ordered it correctly but Porterfield shipped the wrong box. He is going to follow up Monday. Will see what happens.

I may have no option but to wait a day or two without a car. If it is going to be longer than that, I have no idea what I would do.

I suggested to Jerry that he put the Porterfield part numbers in the ordering process and e-mail confirmation so people can verify what comes in the box before actually taking apart the calipers. He says it would help his competitors because it took him long hours of research.

The google search to get the porterfield application PDF took 15 seconds but it does not cover all years to get all the part numbers. The search on porterfield-brakes.com has a "show all" function that will print all models and years and the corresponding part numbers. Go figure.

I wouldn't be too harsh on Jerry... mistakes can happen especially when 2 or 3 links are involved. I ordered pads from Jerry a couple of months ago and the service was great. They arrived from CA to sunny England in 2 days !!
Hope its not too long before your car is back on its wheels...

Always try to order direct.

Less problems.

I ordered front and rear from Porterfield direct.
I mentioned that I was a member of the forum and that the pads were recommended by the members.

They gave me $10.00 discount off each set.

Perfect fit and no problems.

I did try to order from Porterfield directly; some earlier post mentioned that it could be done this way. When I tried to select the pads for my car and buy them, it wanted to route me to another website, and the price was the same as Jerry's.

I won't be hard on Jerry. I'm just glad to know to check out the part number before I tear everything apart.

For parts and ordering info from Porterfield direct

http://www.porterfield-brakes.com/catalog.html

No web ordering (fax, phone and mail only) which seems to be the only value-add Jerry provides at least for ordering the Porterfields for the SLK.

I am not sure ordering directly or through means other than Jerry would have prevented this mistake since Porterfield would have had the same opportunity to make the exact same mistake after they received the order as they did when they received the order from Jerry. Don't know if Porterfield would have been equally responsive if one had to follow up with them directly rather than Jerry do it for you.

Heard from Porterfield directly that they would ship the correct pads today. Just got mail from Jerry with details of the shipment of the correct pads. It was shipped next day air saver so I expect it to arrive Tue evening. They will send a UPS pick up for the wrong ones later.

So far, they have done the minimum they can be expected to do for the mistake.

Any number of things could reduce the chances of such occurrences or its consequences in the future if they are motivated to do. For example, Porterfield implementing additional fulfilment procedures to match the shipment to the order. Or the part number not being kept as a mystery in the ordering process and/or the applications being printed on the box so that the customers could verify the shipment as soon as it arrived rather than scratching the head to see if they are doing something wrong when the pads don't fit and the calipers are dismantled.

Jerry also suggested that many things can go wrong including incorrect pads in the right box so I am not sure one can really be sure until one actually tries to install them. There are no part numbers on the pads themselves. I just hope there is never a situation where the tabs fit but the pads aren't the right ones for the car that leads to either a safety issue or damaged rotors.

I read a few posts last summer about squeeking and Porterfield brakes. I didn't see much of an update after that other than folks using antisqueeking compound... I never saw a name brand. Has anyone asked the dealer to install the Porterfields? Will they? If not, anyone used a national chain like Meineke who specialise in brakes? My dad has volunteered to help me put my brakes on but I'm not very mechanically inclined, and my dad is 70 year old and hasn't worked on a car in 10 years... although he used to rebuild VW bug engines for a living when he was much younger...

If Dad rebuilt bug engines for a living, then the Merc brakes should be a snap. And you should realize, that you are the worker, Dad is the director/advisor on this project. You boys will have a good time![:D]!

fitting pads

I had my Porterfieds fitted by my local MB specialists workshop. They followed the instructions provided with the pads, did all the preperation etc.... no squeaks !! Also, I wasn't supplied one of the anti-squeak products as it comes in an aerosol can which cannot be shipped by plane.
To be honest, i think you and father should be able to fit them. If not, a local workshop will probably do the job cheaper than an MB dealership. And its not exactly rocket-science so trusting a non-MB workshop should be OK, as long as you provide them with the instructions..

When I had reserached before buying the pads, it seemed the squeals were all from the rear wheels and not the front (have no idea why). Since brake dust is not a problem at the rear, one can stay with the OEMs unless the reason for switching is Porterfield performance rather than brake dust.

I have the porterfields on now. Sprayed the silence kit spray on the rotors. No squeals but I am still taking it easy. The worst part is driving around the first 10 miles or so without getting the brakes hot while they are breaking-in. I wonder if the dealers or third-party mechanics take the same care in burning them in. This is one advantage of doing it yourself.

A few notes to add to the excellent procedure on slk32's web site.

1. It is not necessary to remove the torx bolt holding the pad wear sensor from the calipers if you are careful about the caliper removal. There is enough play in it to leave it attached like the brake lines. If you remove the torx bolts do consider replacing them with new ones. The torx bolt head is quite soft and you may land up stripping it.

2. It may be a little difficult to pull the caliper out to get the old pads out if there are any small ridges in the rotors (especially at the edge) where the old pads will catch while being pulled out. You will need to wiggle the calipers up and down and sideways to pull it out. Otherwise, if you are able to compress the piston back a bit through the hole in the calipers, it will help immensely.

3. For those that have not done this before, to reassemble, the inner pads are clipped on to the hollow caliper piston and the outer pads are slipped into the outer caliper lips attached to the rotor assembly before putting the calipers back.

4. It helps a lot to have both wheels in the front off the ground and wheels removed rather than do one at a time since you can swivel the assembly (i.e., turn the wheel to one side or the other) easily this way. Note that you will need to put the ignition key in to unlock the wheels once they are locked in the straight position. I noticed that if the ignition key is out and the wheels are turned, you can still turn them but once they center, they get locked.

5. You have seriously diminished braking power in the first few minutes. So be careful.

6. The inner front porterfield pads have the hole pre-drilled for the sensor.

And finally....

Just make sure you don't have a critical need for the car in the next day or two following the replacement [email protected]% happens. I should know. [:)]

Pads fitted !

I guess a lot depends on how much you trust your workshop. I trust mine 100%, i know they have a strong direction towards quality, so went thro the correct procedure of preperation and bedding in the brakes. I only had the fronts fitted, and I'm really impressed at how little brake dust is on the wheels now, virtually none. I took it easy for about 200 miles, driving quite slowly and easing off earlier etc. Luckily i had no incidents where heavy braking was required. As i live in London, i was actually more concerned by the fact that i wait in lots of traffic queues, where the brake is constantly engaged !!
